Single time point sampling of site characteristics, soil parameters and soil greenhouse gas emissions for extensive and intensive sheep-farming sites in North Wales and Devon, 2016

The data pertains to a single time point 'snapshot' spatial sampling of site characteristics, soil parameters and soil greenhouse gas emissions for two sites (Extensive and Intensive). The extensively managed site ('Extensive'; 240-340 m above sea level; a.s.l.) consisted of an 11.5 ha semi-improved, sheep-grazed pasture at Bangor University's Henfaes Research Station, Abergwyngregyn, North Wales (53°13'13''N, 4°0'34''W). The intensively managed site ('Intensive'; on average 160 m a.s.l.) was a 1.78 ha sheep-grazed pasture located in south-west England, at the North Wyke Farm Platform (NWFP), Rothamsted Research, Okehampton, Devon (50°46'10''N, 30°54'05''W). At the Extensive site soil and gas sampling was conducted on 30th November 2016. At the Intensive site soil and gas sampling was conducted on 1st August 2016. The data contains: site characteristics including elevation, slope, compound topographic index, vegetation type or manure application, and sample point grid references; soil parameters including soil bulk density, soil percentage water-filled pore space, soil moisture, soil organic matter contents, soil pH, soil nitrate nitrogen concentration, soil ammonium nitrogen concentration, soil percentage total carbon contents, soil percentage total nitrogen contents, and carbon to nitrogen content ratio; and soil greenhouse gas flux data for nitrous oxide, carbon dioxide and methane. The study was conducted as a wider part of the NERC funded Uplands-N2O project and BBSRC-supported Rothamsted Research, North Wyke Farm Platform (Grant Nos: NE/M015351/1, NE/M013847/1, NE/M013154/1, BBS/E/C/000J0100, BBS/E/C/000I0320, BBS/E/C/000I0330). Quantifying the spatial and variability of the drivers of greenhouse gas emissions and their interactions in grazing systems is critical to improve our understanding of nitrous oxide, carbon dioxide and methane fluxes, enabling better estimates of aggregated greenhouse gas emissions and associated uncertainties at the landscape scale.

本数据集涉及两个地点（广泛管理和集约管理）在单一时间点‘快照’空间采样下的场地特征、土壤参数及土壤温室气体排放数据。广泛管理地点（简称‘广泛’；海拔240-340米；海拔以上）位于威尔士北部的阿伯甘温格林，班戈大学亨法斯研究站11.5公顷的半改良草地，该草地为羊群放牧地（53°13'13''N，4°0'34''W）。集约管理地点（简称‘集约’；平均海拔160米）位于英格兰西南部，北怀克农场平台（简称NWFP），罗瑟姆斯特德研究站，德文郡奥克汉顿（50°46'10''N，30°54'05''W），该地点为1.78公顷的羊群放牧地。在广泛地点，土壤及气体采样于2016年11月30日进行。在集约地点，土壤及气体采样于2016年8月1日进行。数据包含：场地特征，包括海拔、坡度、复合地形指数、植被类型或粪便施用，以及采样点网格参考；土壤参数，包括土壤容重、土壤孔隙度、土壤湿度、土壤有机质含量、土壤pH值、土壤硝酸盐氮浓度、土壤铵氮浓度、土壤总碳含量百分比、土壤总氮含量百分比，以及碳氮含量比率；以及土壤温室气体通量数据，包括氧化亚氮、二氧化碳和甲烷。该研究作为NERC资助的“高海拔-N2O项目”及BBSRC支持的罗瑟姆斯特德研究站（资助编号：NE/M015351/1，NE/M013847/1，NE/M013154/1，BBS/E/C/000J0100，BBS/E/C/000I0320，BBS/E/C/000I0330）的更广泛研究内容。量化放牧系统中温室气体排放驱动因素的空间分布及其相互作用，对于加深我们对氧化亚氮、二氧化碳和甲烷通量的理解至关重要，有助于更准确地估计景观尺度上的温室气体排放及其相关不确定性。关于此数据集的详细信息，请参阅https://doi.org/10.5285/f3118fa8-6bec-488b-9713-2415912b8b9e。
